Abstract
The utility model provides an automatic anchoring device following a pump used for oil industry, which is composed of a center pipe, a clamping tile, a cone, an oil leakage mechanism, a locking positioning mechanism, etc. The utility model does not need to be matched with other kinds of auxiliary equipment, and is connected to a pump to follow the pump to enter a well, and the utility model follows the pumping of the pump to automatically anchore oil pipe. A packer rubber cylinder can be connected to the upper side of the cone to form an anchoring, sealing and separating integral tool. When the oil pipe is anchored, the oil pipe and a sleeve tube annular space are sealed and separated, and negative-pressure production and pumping isolation are carried out. The utility model is connected with a well washing valve, and can carry out short circuit hot washing. The structure of the utility model is simple. The utility model is convenient to take out and place and has many functions.
Description
The utility model relates to the downhole tool that a kind of petroleum industry is used.
Used tubing anchor in the prior art when going into well, needs be lowered to one-trip string more, even need join the tension force well head usually, can not bend in well with the assurance oil pipe.Some waterpower formula tubing anchor makes oil pipe can not be in effective grappling state because of not having self-locking and oil draining function, causes tubing string to produce wriggling when pumping, has reduced pump efficiency, in order to carry out pump detection and workover smoothly, also need be equipped with bleeder usually in tubing string.Packer is a kind of as negative pressure production or every the downhole tool of taking out, work effectively for making it, the necessary grappling of oil pipe, but usually tubing anchor and packer respectively are integral, and can not carry out work simultaneously, present heat wash tubing string be cup packer join heated scrubing valve or packer (comprising leather cup) join ball-and-seat connect with pump down or use flushing valve separately, these tubing strings are not that complex process is exactly the weak point in application life, do not have anchoring device as cup packer, because of the wriggling of tubing string, leather cup is easy to wear etc.
The purpose of this utility model provides a kind ofly need not join the tension force well head, have self-locking and oil draining function with the automatic anchoring device of pump.
The utility model comprises central tube, slips, cone, sealed packing, it is characterized in that slips ring (2) is by discharging the bottom that shear pin (3) is fixed on central tube (1), slips (5) is fixed on the slips ring (2), cone (6) top that is sleeved on the central tube (1) links to each other with lock ring (11) on the central tube (1), insert in the slips (5) bottom, entrance pressure hole (8) is arranged on the central tube (1), relief hole (10) is arranged on the cone (6), between cone (6) and the central tube (1) sealed packing is housed.
Can connect packing element (7) and gland (9) on the utility model cone (6), and gland (9) is fixed on the central tube (1) with location shear pin (12).
The utility model has the advantages that: 1, do not need other lower tubular column or join the tension force well head, with pumping into well, grappling oil pipe automatically; 2, have pressure release and self-locking mechanism, grappling is reliable; 3, can fuse with packer, the grappling packing is carried out simultaneously; 4, simple in structure, be easy to process and assemble.
Fig. 1 is the utility model structure chart.
Fig. 2 is the utility model example structure figure.
The utility model is described in further detail below in conjunction with drawings and Examples:
The two ends of the utility model central tube (1) are processed with tubing round thread, slips ring (2) is by discharging the bottom that shear pin (3) is fixed on central tube (1), cone (6) is sleeved on the central tube (1) from bottom to top successively with packing element (7), be equipped with between cone (6) and the slips ring (2) on slips (5) and the central tube (1) cone locating ring (4) is set, cone (6), slips (5) and slips ring (2) form shear pin release type dovetail groove slips anchoring mechanism jointly.Packing element (7) upper end links to each other with gland (9), between the top of gland (9) and the central tube (1) lock ring (11) is housed, and gland (9) upper end is fixed both by location shear pin (12).Have entrance pressure hole (8) on the central tube (1), have relief hole (10) on the gland (9).For guaranteeing the sealing between gland (9) and the central tube (1), between is equipped with sealed packing.When oil extraction pump is worked, the oil pipe internal pressure is greater than the pressure of oil jacket annular space, and when this pressure reached certain certain value, the pressure that entrance pressure hole (8) are located acted on the gland (9), cut off location shear pin (12), drag lock ring (11) and move downward, compression packing element (7) makes it be close to casing wall, packing oil pipe and sleeve pipe annular space, cone (6) struts slips (5), and slips (5) is stuck on the internal surface of sleeve pipe, thus the grappling oil pipe.When oil extraction pump worked on, the following confined space that forms of packing element (7) carried out negative pressure production; When packing element (7) was gone up to non-producing horizon, this structure had just satisfied every the needs of taking out.
When the oil well operation (as the inspection pump), on carry oil pipe, because of slips (5) is stuck on the casing wall, make to discharge shear pin (3) and be subjected to shearing force, when the oil pipe upper lifting force when discharging shear pin (3) shear strength, shear pin is cut off, slips ring (2) is descending relatively, and gland (9) is simultaneously descending, and relief hole (10) is connected with entrance pressure hole (8), be about to oil pipe and sleeve pipe annular space and be communicated with, reach the purpose of oil pipe pressure release with the oil pipe inner core; When cone (6) comes downwards to cone locating ring (4) when locating, cone (6) is obstructed and can not be continued descendingly, and that slips (5) and slips ring (2) continue is descending, the state when slips (5) is contracted to into well, on carry oil pipe, just kit can be proposed.
The kit of above-mentioned tubing anchor and packer links to each other with flushing valve (14) by the box cupling (13) of its top, can carry out short circuit heat and wash.When need heat was washed, the pressure of oil pipe and sleeve pipe annular space was greater than the oil pipe internal pressure, and heated scrubing valve (14) is opened, and hot washing lotion just enters in the oil pipe from this valve, and the packing element (7) of heated scrubing valve below has stoped hot washing lotion to be pressed into the stratum, plays the effect of protection oil reservoir.
Claims (2)
1, a kind of with the automatic anchoring device of pump, comprise central tube, slips, cone, sealed packing, it is characterized in that slips ring (2) is by discharging the bottom that shear pin (3) is fixed on central tube (1), slips (5) is fixed on the slips ring (2), cone (6) top that is sleeved on the central tube (1) links to each other with lock ring (11) on the central tube (1), insert in the slips (5) bottom, entrance pressure hole (8) is arranged on the central tube (1), relief hole (10) is arranged on the cone (6), between cone (6) and the central tube (1) sealed packing is housed.
